It really is frustrating to know that after anxiously waiting for the check to be encashed, you will just realize that your application has not not been accepted and returned.
I mailed my application on April 7, 2009 and CIC received it on April 9, 2009. Same as Nix, I also forgot to write the word PRESENT on the employment and address history, and because of such, CIC returned my application and I received it last April 21, 2009. I made an amendment to the form and attached a letter stating that it was an honest mistake. I resent my application last April 22, 2009 and hopefully, things will be OK now.
To Nix: Thanks for starting this thread. I definitely know how you feel right now. Let's just keep our faith intact and we'll surely get there. Goodluck to all of us!
